How to permanently fix AC leak and mold in JLT?« Back to Previous Page

The issue you're describing in your JLT apartment is a common consequence of Dubai's high humidity and year-round reliance on AC systems. The black spots are almost certainly mold, a direct result of the condensation leak providing constant moisture.

To permanently fix this, you must address both the root cause and the existing contamination. First, the AC leak must be stopped. This requires a certified HVAC technician to diagnose the source—often a blocked condensate drain line, a malfunctioning drain pan, or improper installation. They will clear the blockage, ensure the drain pan is correctly sloped, and verify the condensate pump (if present) is operational. Simply cleaning the mold without fixing the leak guarantees its rapid return.

For the mold remediation, this is not a simple cleaning job. The moisture has likely penetrated the drywall, and the mold may be growing within the wall cavity. Effective remediation involves isolating the area, removing and disposing of contaminated porous materials (like damaged drywall and insulation), HEPA vacuuming, and antimicrobial treatment of the remaining structures to eliminate spores. Surface cleaning with bleach is ineffective and can exacerbate the problem by adding moisture.

Given the potential for hidden growth and health risks, a professional inspection is strongly recommended. We at Saniservice are certified to conduct such inspections, including moisture mapping and air quality testing, to determine the full extent of the problem.
